Addressing his first divided Congress, Biden says 'the soul of this nation is strong'

"It's time for a new generation to lead," Sarah Huckabee Sanders said as she wrapped up her remarks giving the Republican response to the State of the Union address . "This is our moment. This is our opportunity."

It will be a generation, she said, "born in the waning decades of the last century, shaped by economic booms and stock market busts, forged by the triumph of the Cold War and the tragedy of 9/11."

"A generation brimming with passion and new ideas to solve age-old problems," she continued. "A generation moored to our deepest values and oldest traditions, yet unafraid to challenge the present order and find a better way forward."

The Arkansas governor, the youngest state leader in the nation, took a moment to tout her soon-to-be-released education proposal. School choice has emerged as a leading Republican issue the past few election cycles, and Sanders said her plan is "the "most far-reaching, bold conservative education reform in the country."

Biden told ABC News' Will Steakin that he thought the reception to his State of the Union speech was “nice” when asked what he thought of the occasionally rowdy reaction from some Republicans while he spoke.

“Rowdy? I thought it was a nice reception," Biden said with a smile and laugh.

His remarks were met with several rounds of GOP interjections, notably when he spoke about how Republicans could try to cut Social Security and Medicare -- although he noted he wasn’t saying the “majority” of Republicans wanted to do so, and Speaker McCarthy has ruled it out.

Sarah Huckabee Sanders, delivering the Republican response to the State of the Union, offered a bleak picture of Biden's presidency.

"In the radical left's America, Washington taxes you and lights your hard-earned money on fire but you get crushed with high gas prices, empty grocery shelves and our children are taught to hate one another on account of their race but not to love one another or our great country," she said. "Whether Joe Biden believes this madness or is simply too weak to resist it, his administration has been completely hijacked by the radical left."

Sanders called Biden "unfit to serve" as she criticized his handling of the southern border, crime, the U.S. withdrawal from Afghanistan and more.

"Every day we are told we must partake in their rituals, salute their flags and worship their false idols," she said of Democrats. "All while big government colludes with big tech to strip away the most American thing there is: your freedom of speech. That's not normal. It's crazy. And it's wrong."

The opposition response to the State of the Union has been around for more than half a century, but in modern times the opposition party has often used it to showcase a new, high-profile figure. It's no different this year, as Republicans were represented by Arkansas Gov. Sarah Huckabee Sanders, who served as a press secretary in the Trump White House.

Sanders just won her new office in November, making her the first woman governor in Arkansas's history. This puts her right at home with many first-term governors, senators and representatives who've given a response speech in recent years. Previous orators include Democratic Gov. Tim Kaine of Virginia in 2006, Republican Sen. Marco Rubio of Florida in 2013, Republican Sen. Joni Ernst of Iowa in 2015 and Democratic Gov. Gretchen Whitmer of Michigan in 2020.

And with the proliferation of response speeches in different languages and from various party factions, even more fresh faces are in the limelight this year. First-term GOP Rep. Juan Ciscomani of Arizona gave the Spanish-language response for his party, while first-term Democratic Rep. Delia Ramirez of Illinois offered the Working Families Party's response.
